The isotopes of hydrogen have different physical properties due to difference in mass. They have almost same chemical properties with a difference in their rates of reactions which is mainly due to.
A
Their different enthalpy of bond dissociation
B
Different electronic configurations
C
Different atomic masses
D
Different physical properties.
Answer
Their different enthalpy of bond dissociation
Explanation
Solution
: Enthalpy of bond dissociation of deuterium is higher (443.35KJmol−1) than hydrogen (435.88KJmol−1) Tritium is radioactive.
